There is a certain difference between the design speed and actual use speed of the Raymond mill. The rotation speed of the small Raymond mill is about 280-220 rpm, the rotation speed of the medium-sized Raymond mill is about 140-180 rpm, and the rotation speed of the large Raymond mill is about 60-120 rpm. The rotation speed of the Raymond mill is directly related to the output and performance of the Raymond mill. The grinding capacity indicators of the Raymond mill mainly have three items: the rotation speed of the central axis of the Raymond mill, the quality of the Raymond grinding roller, and the centrifugal radius of the Raymond grinding roller. The rotation speed of the central shaft is directly related to the use efficiency of the Raymond mill. The same Raymond mill may have different output due to the rotation speed of the central shaft of the Raymond mill. In the process of using the Raymond mill, some customers install their own inverters to easily control the spindle speed

Slag is the residue after beneficiation or smelting. A few years ago, most of the slag produced was discarded or buried, and it was not effectively used, which wasted a lot of resources and polluted the natural environment. In recent years, the particle size of environmental protection has been continuously enhanced. With the advancement of technology, people have a better understanding of slag. We found that slag is an active mixed material of cement after grinding, so the slag in the industry has been integrated in the past two years The utilization rate has been improved, as the main production equipment vertical roller mill in slag processing, has been developed. There are many types of mills on the market, which mills are suitable for processing slag? Investors who invest in the slag processing industry will definitely encounter this problem in the initial stage. Due to the high hardness of slag, it is recommended to use SBM-S slag Mill to process it. SBM-S slag vertical roller m

Raymond milling machine is an ultra-fine milling equipment for processing ore milling. The fineness adjustment range is between 50-400 mesh, and it can be fed into powder once. Raymond mill uses limestone and other ore for processing limestone and other ore, energy saving and environmental protection, small footprint, low energy consumption, simple and efficient. The main components in the Raymond mill are grinding rollers, grinding rings, air ducts, blades, plum blossom frames, main shafts, etc. There are cast iron parts and cast steel parts. Raymond Mill's grinding rollers and rings are mostly made of alloy steel, which is more wear-resistant. Today, I will briefly introduce the method of adjusting the fineness of the processed materials of the Raymond milling machine that many friends have consulted. The fineness adjustment of the Raymond mill is simple as long as the damper is used to control the air volume. Another point is to adjust the fineness of the analyzer by controllin

Due to the special use environment, Raymond mill must be properly treated before and during use. In the selection of materials in the design stage of Raymond mill, the media environment should be considered, and the materials must have good adaptability, corrosion resistance and thermal insulation. In the design of the Raymond mill structure, the welding seam should be minimized to prevent corrosion after penetration. At the production stage of Raymond Mill, we must also pay attention to anti-corrosion work. The mechanical materials should be inspected and registered. We must pay full attention to the anti-corrosion work of Raymond Mill, especially to strictly control the design specifications and design quality. When the Raymond mill is damaged, by repairing or replacing the parts, the Raymond mill can be guaranteed to work normally, that is, under low-cost maintenance, economic efficiency is improved. Then, the necessary maintenance work on the Raymond mill can keep it in good opera

Sand making machine is the most important equipment in the sand and gravel production line, and also the equipment with the most serious loss, usually including plate hammer, counter lining, casing lining and rotor body guard plate. Among them, the failure time of the hammer is the shortest, and the repair cost is quite high. Therefore, the most important thing to solve the high-efficiency wear is to reduce the loss of the hammer. So what exactly causes the Sand Making Machine parts to wear easily? First, the influence of processing capacity and discharge gap. The processing capacity of the sand making machine has a certain influence on the loss of the hammer. When the processing capacity increases, the particle size of the product will become coarse, the crushing ratio will decrease, and the unit wear rate of the hammer will also increase. Changing the size of the discharge gap can also change the thickness of the product size to a certain extent, so it also has a certain impact on t

The main component of limestone is calcium carbonate. Lime and limestone are widely used as building materials and are also important raw materials for many industries. Limestone can be directly processed into stone and burned into quicklime. Lime includes quick lime and hydrated lime. The main component of quicklime is CaO, which is generally massive, pure white, and light gray or light yellow when containing impurities. Quicklime absorbs moisture or adds water to become slaked lime, slaked lime is also called slaked lime, and its main component is Ca (OH) 2. Slaked lime is formulated into lime mortar, lime paste, lime mortar, etc., which is used as coating material and tile adhesive. Limestone can be used in many aspects after being ground by mill equipment, such as plastics, rubber, sealing adhesive materials, paints, paper, ink, etc. Shanghai SBM Machine Co., Ltd. is a mill manufacturer specializing in the development and production of crushing and milling engineering technology p

Any equipment needs daily maintenance to extend the service life of the equipment, and the Sand Making Machine also needs careful maintenance to ensure that it can work normally. With the application of processing equipment, people are paying less and less attention to it, and it is slowly worn down until it is no longer usable, resulting in serious waste of resources. Due to its compact structure and fine production, the sand making machine must be inspected in all aspects before use, the coordination between the components, whether the links are intact, whether the gap is reasonable, and whether the screws between each component are loose We must carefully observe the appearance of the phenomenon and equipment standby conditions. For the management of the sand making machine, we must formulate an effective maintenance plan, according to the maintenance instructions of the machine, and carry out technical exchanges with the machine operator. Sand machine maintenance requires a long t

There are two problems in the process of capital construction in our country: First, large-scale urban construction consumes a lot of natural resources, and at the same time generates a lot of construction waste, and the disposal of construction waste becomes a problem. Second, the urban-rural development is extremely uneven, the economic foundation of the vast rural areas is weak, and the basic construction is obviously lagging behind. Analysis of the above situation, standing at the height of scientific development, from the technical, ecological, economic, and welcoming the feasibility of the mobile crushing station to deal with construction waste to apply recycled concrete to the construction of new countryside. The Construction Waste Crusher not only finds a way out for the treatment of waste concrete, but also solves the problem of the supply of basic materials in the construction of new countryside, and demonstrates the broad prospects of recycled concrete in the construction o

As a modern milling equipment, Raymond mill itself will encounter various problems in the production process, such as performance degradation and wear of wearing parts. Recently, some customers have reported that the fineness of the milling of the Raymond mill is uneven. Then, Shanghai SBM Heavy Industry made an analysis, the specific contents are as follows: 1. Hardness of raw materials For different materials, the hardness is different. The hardness directly affects the grinding difficulty and fineness of the Raymond mill, so the harder the material, the greater the degree of grinding. In the process of using Raymond mill, reasonable ingredients should be used to ensure that the size of the material is uniform and the fineness of the mill. 2. Opening height and size of classifier During the installation of the Raymond mill, if the size of the opening of the classifier is not adjusted properly, it will affect the grinding operation and the fineness of the grinding. Therefore, in the

The finished product of the sand and gravel production line includes both small-grained sand and large-granularity stone. The sieving of the raw material of the finished product is mainly carried out by the round vibrating screen of the sand and gravel production equipment. The production of sand and gravel materials is divided into links such as crushing, screening and VSI Crusher . The quality control of sand and gravel aggregates is mainly based on the particle size and grading requirements of concrete aggregates. Advanced and mature crushing equipment, vibrating screens and standard aperture drying are used to ensure The grading quality standards and regulations determined by the produced concrete aggregate composite specifications. 1. Screen size control: The screen for screening coarse aggregates can be a square mesh screen made of polyurethane material. The size of the mesh is divided into 5mm, 10mm, 20mm, 40mm, 80mm and other specifications according to the aggregate gradation

When buying a Raymond mill, you have a dilemma in terms of equipment price and quality. It is difficult to choose. The better the price is, the more expensive it is. In the current market, price has become the key word to measure the quality of things. According to the current market conditions, the economic status quo in recent years reflects that many customers want to change the original production model and are facing a situation of tight economic conditions. Therefore, I would like to remind you whether you have counted the relationship between price and quality. First of all, low price is the current transaction method for everyone, and seemingly simple requirements are difficult to achieve. For example, buying a Raymond mill is an example. If a customer wants to find a suitable buyer in Shanghai to reach a cooperative relationship, then There are countless large and small manufacturers in Shanghai. More than half of the ideal cooperation is found in many manufacturers, just li
